MVC 4 Using Paged List in a partial View

Question

I am trying to implement PagedList in a partial view.

Describing the view setup. I have Controller A with ViewA. This is the parent view and has its own model. Then I have Controller B with PartialViewB and has its own model as well. Then I have a Div in ViewA that will be used to display the PartialViewB. I can load in PartialViewB after hitting a button and then hide the view after hitting the button again. Within the PartialViewB is the PagedList. Hitting the next page button loads the next page, but loads it in its own page, not in the ViewA as it was before.

I can load up more code as needed, but for now here is the Pager

<br />
    Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

    @Html.PagedListPager(Model, page => Url.Action("ViewComments",
    new { courseID = @ViewBag.courseID, page }), 
    new PagedListRenderOptions { MaximumPageNumbersToDisplay = 5, DisplayLinkToFirstPage = PagedListDisplayMode.IfNeeded, 
        DisplayLinkToLastPage = PagedListDisplayMode.IfNeeded })

::EDIT::

Parent View

<div class="Comments">
    <input type="button" id="View" class="CommentsButton" value="View Comments"/>
    <input type="hidden" id="Hidden" value="false" />
</div>
<div id="Comments">
</div>

PartialView

@model PagedList.IPagedList<QIEducationWebApp.Models.CourseComment>
@using PagedList.Mvc;

@{
    ViewBag.Title = "Comments";
}

<h2>Comments!</h2>

<table>

@foreach (var item in Model)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.CommentDate)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.UserName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CommentText)
        </td>
    </tr>
}

</table>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

<appSettings>
  <add key="UnobtrusiveJavaScriptEnabled" value="true"/> 
</appSettings>

<br />
    Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

    @Html.PagedListPager(Model, page => Url.Action("ViewComments",
    new { courseID = @ViewBag.courseID, page }),
            PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing(
                new PagedListRenderOptions { MaximumPageNumbersToDisplay = 5, DisplayLinkToFirstPage = PagedListDisplayMode.IfNeeded, 
                DisplayLinkToLastPage = PagedListDisplayMode.IfNeeded },
                new AjaxOptions() { HttpMethod = "GET", UpdateTargetId = "Comments" }))

This will use unobtrusive ajax to do the replace for you. You just need to handle the fetch and skip on your end and send back the new partial view along with the model.

@Html.PagedListPager(Model, page => Url.Action("ViewComments", page }), PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing( new AjaxOptions(){  HttpMethod = "GET", UpdateTargetId = "partialContainerYouNeedToReplace"}))

Make sure that you have unobtrusive js referenced on your page when doing this. It comes with MVC out of the box and you should just need to reference the bundle.

Hope this helps.
